CEMENT-BLOCK MACHINE.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed February 13, 1905. Serial No. 245,487.

To all whom it may concern:

Be it known that I, GORMAN J. APGAR, a citizen of the United States,residing at Bobinson, in the county of Crawford and State of Illinois,have invented a new and useful Ce-.

ment-Block Machine, of which the following is a specification.

This invention relates to an improved mold for making artificial-stonebuildingblocks, and has for its object to provide an inexpensive,durable, .and. eflicient mold of this character by means of which eitherhollow or solid building-blocks of different sizes and shapes may beconveniently and expeditiously manufactured.

A further object of the invention is to provide a mold having pivotedside and end walls movable to open and closed positions through themedium of a vertically-slidable operating-frame.

A still further object is to provide a pivoted connection between theoperating-frame and the walls of the mold wherebywhen said frame isdepressed the pivoted walls will be swung inwardly and assembled topermit the formation of the block, and when the frame is elevated saidwalls will be swung outwardly to thereby permit the discharge of themolded product.

l/Vith these and other objects in view the invention consists in theconstruction and novel combination and arrangement of parts hereinafterfully described, illustrated in the accompanying drawings, and pointedout in the claims hereto appended, it being understood that variouschanges in form, proportions, and minor details of construction may beresorted to without departing from the principle or sacrificing any ofthe advantages of this invention.

In the accompanying drawings, forming a part of this specification,Figure 1 is a perspective view of a mold constructed in accordance withmyinvention. Fig. 2 is asimilar view showing the walls of the mold inposition to release the block. Fig. 3 is a transverse sectional view.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawmgs.

The improved mold comprises a rectangular hopper 5, to the corners ofwhich are riveted or otherwise rigidly secured loops or brackets 6,adapted to receive supporting legs or uprights 7, the latter beingpreferably tubular in form and rigidly secured in said loops orbrackets, so as to support the hopper in elevated position. Fastened tothe sldes of the hopper are hinges 8, to which are secured the movableside walls 10 of the mold, while pivoted to the opposite ends of thehopper, as shown at 11, are the movable end wall 1.2 of said mold. Alongitudinal reinforcingstrip 9 is also preferably secured to the hingesand to the side wall of the hopper to thereby form a brace or supportfor the latter.

Spaced from the side and end walls of the mold is an operating-frame 13,provided with openings 14 tor the reception of the uprights 7 and uponwhich said frame is mounted for vertical movement. Secured to theopposite ends of the frame 13 are vertical rods 15, the free ends ofwhich are spaced from the end walls of the hopper andterminate insuitable handles 17, by means of which said frame may be convenientlyoperated to open and close the walls of the mold, as will be more fullyexplained hereinafter.

Riveted or otherwise rigidly secured to the bottom of theoperating-frame, at the sides thereof, are loops or eyes 18, eachadapted to receive one end of an angularly-disposed link 19, theopposite end of which engages a simi lar eye or loop 20, secured to theside wall 10 of the mold. Secured to the opposite ends of the frame aresimilar eyes or loops 21, supporting corresponding angular links22,which are in turn pivoted in eyes or loops 23, fas tened to the endwalls 12 of the mold. The links 19 and 22 form pivotal connectionsbetween the operating-frame and the .walls of the mold, so that whensaid frame is elevated by exerting an upward pull on the handles 17 theside and end walls of the mold will be swung outwardly to open position,as clearly shown in Fig. 2 of the drawings, and when said frame isdepressed the walls will be swung inwardly in contact with each other,to thereby permit the formation of the block. The arrangement anddisposition of the links 19 and 22 are such that when the pivoted wallsof the mold are assembled or in closed position the links will assumepositions substantially parallel with the bottom of the operating-frameand when the latter is elevated will exert an outward pull on the wallsof the mold by reason of the pivotal connections between said links andthe supporting eyes or loops.

In manufacturing the blocks the mold is placed upon a platform, table,or other suit able support, upon which has been previcut or chipped rockor other ornamental de-.

ously placed a suitable pallet and the cement, concrete, or otherplastic material shoveled or otherwise introduced into the mold andthoroughly tamped in any wellknown manner. After the block is formed anupward pull exerted on the handles 17 will release the walls of the moldand elevate the latter from the platform or table, thereby permittingthe molded product to be conven iently carried on the pallet to thedryingracks or other suitable place until ready for use. Hollowbuilding-blocks may be readily formed by placing the usual cores in themold preparatory to introducing the cement, and said blocks, whetherhollow or solid, may be molded with an exterior finish in imitation ofsigns by inserting in the mold a pattern or die plate having the desireddesign stamped, embossed, or otherwise imprinted on the face thereof.

From the foregoing description it will be seen that there is produced anextremely simple and inexpensive mold admirably adapted for theattainment of the ends in view.

Having thus described the invention, what is claimed is 1. A moldcomprising a hopper, side and; end walls pivoted thereto, and avertically slidable operating member for moving said walls to open andclosed positions.

2. A mold comprising a hopper, side and end walls pivoted thereto, avertically-slidable member for moving said walls to open and closedpositions, and means for operat ing said member.

3. A mold having movable walls, an operating member surrounding saidwalls and adapted to move the latter to open and closed positions, and apivotal connection be end walls pivoted to the hopper, uprights forsupporting said hopper, a frame mounted for vertical movement on theuprights, and links pivoted to the frame and walls ,respectively.

8. A mold comprising a hopper, side and end walls pivoted to the hopper,uprights for supporting said hopper, a frame mounted for verticalmovement on the uprights, and handles secured to the'frame forreciprocating the latter to thereby open and close said walls.

9. A mold comprising a hopper, side and end walls pivoted to the hopper,uprights for supporting said hopper, a frame mounted for verticalmovement on the uprights, a pivotal connection between said walls andframe,and means for limiting the vertical movement of the latter.

10. A mold comprising a hopper provided with supporting-brackets, sideand end walls pivoted to the hopper, uprights seated in said brackets, aframe surrounding the pivoted Walls and provided with openings for thereception of the uprights, links pivoted to the walls and frame,respectively, and rods carried by the frame and having their free endsprovided with terminal handles.

11. A portable mold comprising a hopper having side and end wallspivoted thereto, and a combined carrying and operating member servingduring its initial movement to move said Walls to open and closedpositions.

12. A portable mold comprising a hopper having side and end wallspivoted thereto, a vertically slidable operating member for moving saidwalls to open and closed positions, and handles carried by the operatingmember for elevating and carrying said mold.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.
